Actuators SA and SAR

Actuators SA and SAR

Actuators of the SA type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min. A special version for longer running is available for the S2 - 30 min duty.

The modulating actuators of the SAR range are rated for class C or types of duty S4 - 25 %. Special versions for S4 - 50 % and S5 - 25 % are also available

Actuators of type range SA/SAR can be combined with various controls from simple OPEN-CLOSE control to the micro-controlled version with logging of operating data or fieldbus interface.

Actuators of the SAV type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min. A special version for longer running is available for the S2 - 30 min duty.

The modulating actuators of the SARV range are rated for class C or types of duty S4 - 25 %. Special versions for S4 - 50 % and S4 - 75 % are also available

Explosion-proof versions SAEx and SAREx

Explosion-proof versions SAEx and SAREx

Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.

Certification is performed in close collaboration with national and international certification bodies.

FQM and FQMEx fail safe unit

FQM and FQMEx fail safe unit

With their new FQM fail safe unit, AUMA offer innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy.

Constant torque curve with torques from 150 Nm to 1,200°Nm

The spring is not operated during standard operation. Thanks to the overriding gear arrangement, the constant force spring is disengaged during normal operation and does not need to be operated.

The end position switches are automatically set during the setting procedure of end positions OPEN and CLOSED and do not require separate adjustment

Actuators SQ and SQR

Actuators SQ and SQR

Actuators of the SQ type range for open-close duty and positioning duty are rated for class A and B or types of duty S2 - 15 min.

The modulating actuators of the SQR range are rated for class C or types of duty S4 - 25 %.

Actuators of type range SQ/SQR 07.2 – SQ/SQR 14.2 can be combined with various controls from simple OPEN-CLOSE control to the micro-controlled version with logging of operating data or fieldbus interface.

Combinations with linear thrust units

Combinations with linear thrust units

globe valves, the multi-turn actuator SA can be combined with the linear thrust unit LE. In case a lever arrangement has to be operated, the linear thrust unit can be mounted on a base.

Spur gearboxes GK

Spur gearboxes GK

GK bevel gearboxes will be used if the operating direction is to be displaced by 90°. Thus, the output torque can be increased many times.

Multi-turn gearbox GHT

Multi-turn gearbox GHT

High pressures call for multi-turn actuators providing high torques. By combining a multi-turn actuator with a GHT multi-turn gearbox, the torque range can be expanded to 120,000 Nm.
